Dometic RV Toilet Water Valve Assembly OEM 385314349 — Gravity-Flush Replacement with Screws Included

Genuine Dometic water valve assembly that replaces the factory valve on compatible gravity-flush RV toilets to stop leaks and restore reliable flush performance.

This OEM Dometic Water Valve Assembly (part number 385314349) is a full replacement kit engineered for gravity flush toilet models (excluding 300 and 400 Series). It replaces the entire valve mechanism so you avoid piecemeal repairs that can leave hidden leaks or uneven water delivery. The kit ships with the factory-fit parts, replacement screws, and installation instructions so the job is straightforward for most RV owners and service techs.

What does this Dometic valve assembly fix?

The assembly addresses worn or damaged toilet valves that cause leaking, weak or uneven flushes, and intermittent filling problems. By swapping the entire valve unit, you restore the original flow path and seal surfaces without needing custom adjustments. This reduces repeat service visits and helps preserve connected toilet components.

• Replaces worn seals and internal valve components in one step
• Stops common sources of slow leaks and water loss
• Re-establishes consistent flush pressure and distribution

Which toilets are compatible with this Dometic replacement?

This OEM assembly is intended for Dometic gravity-flush models except the 300 and 400 series. The product listing and part references (90626, 980, 911, 902, 1606, 710, 1006, 1048, and many others) indicate the models this assembly fits directly.

How difficult is installation and what’s included?

Installation is designed to be user-friendly: the complete valve assembly arrives ready to drop in and fasten using the supplied screws. Typical installs require basic tools and follow the included instructions; an afternoon is usually enough for a DIYer or service technician. Because it’s a full OEM valve, no additional parts or sealants are normally needed.

• Complete valve assembly replaces the entire unit
• Included replacement screws and step-by-step instructions
• Simple hand tools usually suffice for installation

Why choose a genuine Dometic replacement instead of aftermarket parts?

Genuine Dometic components are engineered to match the original tolerances, materials, and safety specifications. That fit and material match reduces installation issues and helps maintain the toilet’s designed performance and durability. Using the factory part also helps preserve warranty coverage and avoids compatibility surprises that can arise with non-OEM parts.

• Factory-direct design for accurate fit and function
• Maintains original performance and material standards
• Helps protect warranty and reduces risk of follow-up repairs

Who this is for: RV owners, fleet maintainers, and service technicians who want a reliable, factory-correct replacement for a failing gravity-flush toilet valve will benefit from this Dometic OEM assembly. It’s ideal if you need a complete swap to restore consistent flush pressure and stop leaks without trial-and-error repairs. Choose this part when you want a direct-fit repair that matches the original manufacturer's specification and includes the hardware to finish the job quickly.
